OBJECTIVE The study examined the validity of simple and novel measures of generalized obesity- [body mass index (BMI, kg/m2), fat mass index (FMI, kg/m2), and body fat percent (BF%)] and central obesity--[waist circumference (WC, cm), waist-hip ratio (WHR), and waist-to-height ratio (WC/ht ratio)] against BF% and BMI as criteria. It also aimed to predict fat-free mass index (FFMI, kg/m 2 ), FMI...

OBJECTIVE To identify a body fat percentage (%BF) threshold related to an adverse cardiometabolic profile and its surrogate BMI cut-off point. DESIGN Cross-sectional study. SETTING Two public schools in poor urban areas on the outskirts of Guatemala City. SUBJECTS A convenience sample of ninety-three healthy, prepubertal, Ladino children (aged 7-12 years). RESULTS Spearman correlations ...

Obesity is a significant problem affecting United States (US) firefighters. While body mass index (BMI) is widely used to diagnose obesity, its use for this occupational group has raised concerns about validity. We examined rates and types of misclassification of BMI-based obesity status compared to body fat percentage (BF%) and waist circumference (WC). Male career firefighters (N = 994) from ...

BACKGROUND Body Mass Index (BMI) is used as a useful population-level measure of overweight and obesity. It is used as the same for both sexes and for all ages of adults. The relationship between BMI and body fat percentage (BF %) has been studied in various ethnic groups to estimate the capacity of BMI to predict adiposity. We aimed to study the BMI-BF% relationship, in a group of South Asian ...

BACKGROUND Obesity is a global epidemic, which is a risk factor for cardiovascular diseases and metabolic abnormalities. It is measured by body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), body fat (BF) distribution and abdominal fat mass, each having its own merits and limitations. Variability in body composition between ethnic groups in South-Asians is significant and ma...

Body mass index (BMI) is widely used as an index of obesity in adults. In trained population, individual with low body fat could be classified as overweight by BMI. To evaluate this problem, the purposes of this study were to determine the BMI and body fat percentage (BF%) of trained and untrained subjects and to evaluate the accuracy of BMI classification (> or =25 kg.m(-2)) as a prediction of...

BACKGROUND Emerging evidence suggests that a mildly elevated body mass index (BMI), is related to improved survival and fewer cardiovascular events in patients with coronary artery disease (CAD). We hypothesize that these results are related to the poor diagnostic performance of BMI to detect adiposity, especially in the intermediate BMI ranges. METHODS AND RESULTS A cross-sectional study of ...

Associations between body mass index (BMI), body fat percentage (BF%), and health risks differ between Asian and European populations. BMI is commonly used to diagnose obesity; however, its accuracy in detecting adiposity in Koreans is unknown. The present cross-sectional study aimed at assessing the accuracy of BMI in determining BF%-defined obesity in 6,017 subjects (age 20-69 yr, 43.6% men) ...

PURPOSE Popular generalized equations for estimating percent body fat (BF%) developed with cross-sectional data are biased when applied to racially/ethnically diverse populations. We developed accurate anthropometric models to estimate dual-energy x-ray absorptiometry BF% (DXA-BF%) that can be generalized to ethnically diverse young adults in both cross-sectional and longitudinal field settings...
